pubmed-article:6175743 | pubmed:abstractText | 1. Isolated mouse pancreatic acini were used to investigate the effect of secretagogues on acinar cellular electrolytes and cell pH. The effect of changes in the acid-base status of the incubation medium on acinar cellular electrolytes, cell pH and amylase release were also studied. 2. Carbachol at concentrations of 10(-6) or 10(-5) M was without any effect on the intracellular concentrations of total Na+, Na+ exchangeable with 22Na+, K+ and Cl-, and did not influence cell pH as determined by the DMO method. 3. Changes in pHe achieved by varying the HCO3- concentrations at constant CO2, varying the CO2 concentration at constant HCO3- or by titration of a HCO3-/CO2 free HEPES buffered medium did not influence intracellular electrolyte values. 4. pHi changed linearly with pHe by about 1.2 units/pHe unit change over the pHe range of 7.7--6.5. pHi, however, did not change in response to a change in the CO2 tension when the HCO3- concentration was adjusted to keep pHe at 7.4. 5. Lowering pHe below 7.1 inhibited carbachol and CCK8-stimulated amylase release. By contrast a decrease of pHe to 6.8 was without significant effect on basal and secretagogue increased 45Ca2+ efflux from pancreatic acini. 6. In conclusion the pH sensitivity of amylase release by acinar cells is probably related to changes in pHi. Since Ca2+ mobilization is not affected, the pH sensitive step is probably in the mechanism by which Ca2+ activates the release of zymogen granules contents by exocytosis. | lld:pubmed |
